TO ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:

Be it known that I, GILBERT B. FRENCH, of Dunbarton, of the county ofMerrimac, of the State of New Hampshire, have invented a new and usefulimprovement in Car-Couplings; and do hereby declare the same to be fullydescribed in the following specification and represented in theaccompanying drawings, of which Figure 1 is aside elevation.

Figure 2, a longitudinal section of it. 7

Figure 3 is a horizontal section taken'through its link=pinholding-jaws.

V Figure 4 is a front View; and

Figure 5 is a side elevation of the link-pin.'

In such drawings, A denotes the hunter-head or bar, to which the link isto be coupled. This bar is provided with a link-receiving chamber, a.Within the said chamber is an abutment, b, which is supported againstone or more springs, 0, arranged between it 'an'd the rear end of thechambein- Fromthe said abutment a' standard, d, extends upward, and iswedge-shaped where it goes between the, two jaws B B, which are arrangedon the top of the hunter-bar, and turn on centres, e' 0, arranged at ornear their rear ends. These jaws have esprings, ff, applied to them andthe bar, such springs being for closing" the jaws upon the link-pin C,which,

when in its highest position, they seize by entering two notches, h it,made in its opposite sides and near its lower end. The said link-pin Ialso form with a shoulder, i, which, when the pin drops down into thehunter-bar and through the link, will rest on the latter and hold it ina horizontal position. Leading from the jaws down through the hunter-baris a passage, is, for-the reception ofthepin, such passage beingeontinuedup through a cap, Z, which covers the jaws and their springs,and is provided with a chamberfliz, for their reception. When thelink-pin is raised, the'jaws, by graspingit within its notches, willhold it in itselevated position. Under these circumstances, if a link bepassed into the hunter-bar and against th'e abutment, the latter, withits wedgeshaped-standard, will be driven backward and will force thejaws apart so as to disengage them from the pin, which, by its gravity,willnext fall down into and through the link, so as to connect it withthe bar I am aware that spring jaws to catch and hold a substitute for alink have been applied within the main chamber of a draw-bar orhunter-bar, and therefore I do not claim such. I employ the jaws in aseparate cham her, a, for supporting the'link-pin, as described; and Ialso employ the spring abutment and its wedge-shaped standard foropening the jaws, the same enabling nie to use a common open link.Therefore I What I claim as my invention or improvement, is, thearrangement of the spring jaws,.th c spring abutment, and the wedgedstandard, together and with thebunte'r-bar and its pin passage, asset-forthh GILBERT B. FRENCH.
